Guess my next step is to replace the 100uF Elna Silmics and go for the Black Gate N's, then look into getting a dedicated chassis made. Currently my Audiosector kit is just in a Hammond Chassis from Maplins. Very small and no heatsink (using the chassis for that!).

If you want to use each LM4780 chip to amplify one channel you have a choice of either parallel or bridged configurations.

The parallel is easier to implement, as it runs from single ended source and basically there are no limits as to the speaker impedances.

The bridged configuration will sound better, but you need to supply balanced signal to the amp (as amp itself does not do conversion) and the speakers shouldn't go below 6 ohm.

In the commercial amps I leave the plastic on, if I build for my own use, I remove it.

How much is the full case for the dac? Is there anyway to have the plug on the back ? Not sure if it will fit in my cabinet with wires sticking out of both sides. I am replacing a dac that decides every now and again that I like distorted music(Audio Alchemy) so my wires are just the right length.
Thanks

If you need everything in a back, I would suggest using green board and standard case of suitable size.

Below is a nice example how it can be implemented:

If you want to go with Premium DAC board and one of my custom DAC chassis, I'm afraid it's not possible, as you would need to run sensitive signal cables right beside transformer; there's also not enough space on a single pannel for signal and power connectors:

unless you would do it like this (with permanent power cord):

I really like the way the case looks with the wooden sides. Does the price depend on what wood option i go with ? I might position it sideways just so I can have the nicer case ,I think that would work. so what would a premium kit with a case cost?
Thanks

The Premium kit is $230, Hammond transformer adds another $30 and Cardas dual RCA $20. Each chassis is build to custom order, so e-mail me with regards to prices and options.
